Dengue is a mosquito-borne disease, which is common in tropical and subtropical countries of the world. The climatic conditions of these nations are favorable for the growth and survival of the mosquito that carries the dengue virus. In India, the cases of dengue fever are highest after the monsoon season. In the 1950s, severe Dengue was recognized for the first time in the Philippines and Thailand, but it has now spread across most countries in Asia and Latin America. People from other countries also develop this fever if they travel to tropical areas. The cases of Dengue have dramatically increased across the whole world in recent decades.
